Flower Embellishments
Choose premade felted flowers and leaves, make your own using pieces of felt, or use old woolen sweaters that have been felted. 

To felt sweaters: Wash 100% wool sweaters in medium water temp with a mild laundry soap two to three times. Check the density of the sweater after each cycle to see if it is thick enough. Dry sweaters gently in dryer. This will shrink the sweaters and bind the wool fibers so you can cut the wool without it fraying. 

Cut out templates and place on the back side of the felted wool and pin. Cut out 3 to 5 flowers and 5 to 7 leaves. Cut out several thin strips of felt approximately ¼" wide for stems and center of flowers.  

Place flowers and leaves onto slippers and pin down or adhere with a small drop of fabric glue to hold in place while you sew on. See photo for placement.

With needle and floss or yarn, sew a running stitch around the outside of each leaf and flower. Coil strips and sew down to center of flowers with needle and thread. 

Care Instructions
Slipper sock soles are hand washable with mild detergent. Consider the yarn you used to make your slipper socks before washing. After washing and rinsing, gently squeeze out excess water. Stuff with clean paper or cloth to retain shape. Allow to air dry.


Collect bright colors of wool sweaters when you find them so you will have them any felted project that comes up.
